On my new bike i am using the Magicshine http://www.dealextreme.com/p/ssc-p7-2-xp-e-16w-3-mode-1400-lumen-led-bike-light-set-4-18650-included-36018 but the mount is not steady enough for a ride on a bumpy road (in the woods). I would not recommend that light, because i am only using the big led in the middle, the two smaller leds only give a bit of light just in front of the bike. So if you want to buy something like that, don't spend so much money for a light with three leds, one is enough.
I imagine that this is a good way of losing tailcaps and batteries. Thinking of all the tools and spares I've lost when motorcycle electrics were playing up.
I'm thinking about a flashlight with R5 led and 18650 battery. I already have a uf 504b and i would like to use this. I will take a back-up battery but i don't need many hour of light. Just the time to come home if i am in the wood and the sun goes down.
My first need is that the flashlight stay in place all the time, also after many bumps.
Do you think i can damage the led or the flashlight on a bumpy road?
Thanks again. Really impressive your "light pack" Be-Seen Triker! I think i'ts impossible not to see you even in the darkest night!!
I think i'll try with 504 and DX mount but i also will try to make an helmet light like Be-Seen Triker. In this way i can have twice the runtime or more power if i need it.
